I am preparing to upgrade to 2.5AE from 2.3.1, primarily for the rounded corners (which I have been wanting for a long time as they'll match my layout and look more modern).

But when I look at the sample image of 2.5AE, I am seeing only an old-school gray skin. Has this particular version been moded or what? At the bottom is says this is YaBB Next Edition, not 2.5AE. What is this?
